What to do when your landlord ignores your CAM dispute letter draft. Step-by-step escalation: follow-up notices, formal audit, ADR, and litigation.
TL;DR: If your landlord does not respond within 30 days of your stated deadline, send a follow-up notice, then formally invoke your audit rights clause to compel records. After that, escalate to mediation or arbitration as your lease requires. Do not withhold rent. A documented non-response strengthens your position in any subsequent proceedings.
Run the audit before you decide whether this applies to your lease.

Find My OverchargesSee a sample report firstA situation where a commercial landlord fails to reply substantively to a formal CAM dispute letter draft within the specified response period. Non-response does not resolve the dispute or waive the tenant's rights, but it does require the tenant to escalate through a structured sequence: follow-up notice, formal audit rights invocation, and alternative dispute resolution or litigation.
“CAMAudit produces a documented calculation tenants can reference in every follow-up they send. When a landlord ignores three written contacts that include specific dollar calculations and lease citations, the paper trail that builds is exactly what mediators and courts want to see.”
A landlord who ignores your CAM dispute letter draft is not necessarily being evasive, sometimes property management teams are understaffed, letters get routed incorrectly, or the dispute landed in someone's inbox who isn't sure what to do with it. But after 30 days with no response, you need to escalate. Here is the path.
Before assuming your landlord is ignoring you, verify delivery. If you sent the original letter by certified mail, check the USPS tracking record and confirm the delivery date. If you sent by overnight courier, pull the delivery confirmation. If the delivery record shows the letter was received but no response came, proceed to step 2.
If the delivery record shows the letter was returned undeliverable, the wrong address, the recipient had moved, the property management company had changed, you may need to resend. Check the lease's Notices clause for the current required address. If the landlord's address has changed and the lease hasn't been updated by a formal amendment, sending to the original address in the lease may still satisfy your contractual obligation. Document your attempt.
Thirty days after the original deadline with no response, send a second written notice. Reference the original letter by date and your stated deadline. Keep it brief:
"This follows our letter dated [original date] disputing $24,000 in CAM overcharges for the 2024 reconciliation period. The deadline for your response was [date]. We have not received a response. Please confirm receipt of our original letter and provide your substantive response within 15 days. If we do not receive a response by [new date], we will proceed with a formal audit request under Section 8.3(d) of the Lease."
Send this the same way as the original: certified mail, overnight courier, or whatever your lease requires. The paper trail matters, if this dispute eventually goes to mediation or litigation, the timeline of your attempts to resolve it in good faith is relevant evidence.
Most commercial leases include an audit rights clause that entitles the tenant to inspect the landlord's accounting records supporting the CAM reconciliation. If you have not already done so, now is the time to invoke this right formally.
A proper audit rights invocation is a separate written notice that:
Most audit rights clauses require the tenant to give notice within a specified window (often 90 to 180 days of receiving the reconciliation statement). If you are still within that window, invoke now. If you are past it, check whether your lease has a broader dispute resolution provision that is separate from the reconciliation audit window, some do.
Once you formally invoke audit rights, the landlord's obligation to cooperate with the audit is a lease covenant. Failure to provide records is itself a potential breach, which gives you additional leverage and a separate legal claim.
Most commercial leases require some form of dispute resolution before litigation, mediation is common, binding arbitration is increasingly standard.
Mediation is non-binding: both parties present their positions to a neutral mediator, who facilitates negotiation. AAA data shows that commercial mediations resolve within a median of 114 days, and roughly half to two-thirds of business disputes settle before or at the hearing. Mediation is less expensive than litigation and keeps the relationship intact. If your lease requires mediation before any other escalation, trigger it in writing by the process specified in your lease.
Arbitration is binding: a neutral arbitrator (or panel) hears both sides and issues an enforceable award. AAA's 2024 data show median time to award in B2B arbitrations ranging from approximately 2 to 19 months depending on claim size. Arbitration is faster than federal court litigation (median time to jury trial is roughly 32 months) but can be expensive if the claim is large enough to require in-person hearings.
Neither option is available if you ignore the contractual sequence. If your lease says mediation first, you cannot bypass it and file in court without risking your case being dismissed for failure to exhaust dispute resolution requirements.
If mediation fails or the lease does not require it, and the claim amount justifies the cost, litigation is the final option. A few things to know before going this route:
Small claims or limited jurisdiction court handles CAM disputes under roughly $10,000–$25,000 in most states. No attorney required, faster resolution, lower cost.
Breach of contract litigation for larger claims can be filed in state court. You are claiming that the landlord's overcharge breached the lease's operating expense provisions. Discovery, the formal process of requesting records, gives you access to the full accounting ledger you may not have gotten through the audit rights process.
Seek declaratory relief if you want a court to establish the correct calculation methodology going forward, not just recover past overcharges.
Attorney fees matter. Some commercial leases include fee-shifting provisions that allow the prevailing party to recover attorney fees. If yours does and your claim is well-documented, the landlord's calculus on settlement changes significantly.
Do not withhold rent. In commercial leases, the obligation to pay rent is an independent covenant. Withholding rent to force resolution of a CAM dispute has backfired spectacularly in documented cases. In Tolou Realty Assocs. v. Dolphin Diner Corp. (N.Y. App. Term, 2025), tenants who withheld rent pending a dispute were ordered to pay over $721,000 in arrears and vacate the premises. The CAM dispute did not excuse the nonpayment. Pay what is documented and undisputed while pursuing the overcharge separately.
Do not make threats you cannot back up. Threatening to report a management fee calculation error to state regulators is not credible and undermines the rest of your letter. Stick to remedies that are actually available under your lease and applicable law.
Do not let the dispute drag past your windows. If your lease has a 90-day audit window or a 120-day dispute window, every day you wait is a day you may be losing your contractual right to dispute. Document your timeline carefully.
Do not ignore a landlord response that disputes your math. If the landlord responds with a different calculation, you need to engage with it specifically. A landlord who provides a substantive response has moved into negotiation, not avoidance.
